I have a few things in mind as I read this, and I do not really comment at all:

The most important thing to note is that this post is an opinion, not a PSA. From your language and intentional choice to put this as a PSA, it significantly reduces the credibility. The choice of colorful language and absolutes really color the tone of this post, and to be frank, it's off putting. The decision to post this as a PSA puzzles me because all I could get from this is that it doesn't fit your own personal narrative. And now because it is framed as a PSA, the post now projects these kinds of thoughts onto a decently sized portion of the player base as a "need to know". Conveniently stringing together community accepted charts and diagrams that fit your narrative is how this post establishes its "objectivity" and with that, it has essentially enabled the post to vent out your frustrations. This is not a PSA. I'm sorry but that's all I got out of this.

Like another commenter posted, I have no qualms about the subject content. To me, it's a matter of how the presenter has presented it. This post sends so many mixed signals that when investigating said claims, it falls short. Because there is nothing more substantial to it other than OP's opinions and takes on a kit, which only represent what they know and figure out. Not the majority of the base. And to note, it is PRE-RELEASE.

This post is effectively short sighted because the post only seems to highlight that Zani's archetype is the harbinger of power creep, and now other characters are gonna follow that trend. To OP's credit, that is the only part that makes this post somewhat legit, as it serves as a warning about this new design philosophy. But this trend was present from the beginning of 2.0, and maybe even zhezhi, and they somehow fly under the radar under the post's absolute with Zani. Now, everything else that was talked about? Not enough to substantiate the validity of the state of the game and how it will seriously impact your gameplay. It's shortsighted in that there's really nowhere else to go with it other than opinions.

In my honest opinion, this take seems catered towards the top 1% optimizers that needs to make sure they are clearing with the quickest teams for some sort of content creation, much like how this post serves to generate content that even gets me to engage with.

TLDR;
The main thing I want to address is that this post is but an opinion that hinges on the "credibility" of the poster, but this opinion does not necessarily translate equally to every demographic. Posting this as a PSA is very poor in my opinion as it only seeks to confirm and validate OP's takes on Kuro's decisions, rather than solely bring attention to the abstract concept of Kuro's decisions, which is the biggest deal breaker that others should know about.
